The shoots of Salvia officinalis growing in MS liquid medium supplemented with IAA 0.1 mg l-1) and BAP (0.45 mg l-1) were treated with methyl jasmonate (MeJA) to increase production of compounds with antioxidant activity (carnosic acid, carnosol and rosmarinic acid). The increase in metabolite production depended on MeJA concentration, the period of exposure to elicitor and type of compound. Th...
